Merge branch 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

Pull the MCA deletion branch from Paul Gortmaker:
 "It was good that we could support MCA machines back in the day, but
  realistically, nobody is using them anymore.  They were mostly limited
  to 386-sx 16MHz CPU and some 486 class machines and never more than
  64MB of RAM.  Even the enthusiast hobbyist community seems to have
  dried up close to ten years ago, based on what you can find searching
  various websites dedicated to the relatively short lived hardware.

  So lets remove the support relating to CONFIG_MCA.  There is no point
  carrying this forward, wasting cycles doing routine maintenance on it;
  wasting allyesconfig build time on validating it, wasting I/O on git
  grep'ping over it, and so on."

Let's see if anybody screams.  It generally has compiled, and James
Bottomley pointed out that there was a MCA extension from NCR that
allowed for up to 4GB of memory and PPro-class machines.  So in *theory*
there may be users out there.

But even James (technically listed as a maintainer) doesn't actually
have a system, and while Alan Cox claims to have a machine in his cellar
that he offered to anybody who wants to take it off his hands, he didn't
argue for keeping MCA support either.

So we could bring it back.  But somebody had better speak up and talk
about how they have actually been using said MCA hardware with modern
kernels for us to do that.  And David already took the patch to delete
all the networking driver code (commit a5e371f61ad3: "drivers/net:
delete all code/drivers depending on CONFIG_MCA").

* 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:
  MCA: delete all remaining traces of microchannel bus support.
  scsi: delete the MCA specific drivers and driver code
  serial: delete the MCA specific 8250 support.
  arm: remove ability to select CONFIG_MCA

-	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
-	  are assigned to the drive letters, starting with the lowest SCSI-id
-	  (physical number -- pun) to be drive C:, as seen from DOS and
-	  similar operating systems. When looking into papers describing the
-	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
-	  The SCSI-standard follows a hardware-hierarchy which says that id 7
-	  has the highest priority and id 0 the lowest. Therefore, the host
-	  adapters are still today everywhere placed as SCSI-id 7 by default.
-	  In the SCSI-standard, the drive letters express the priority of the
-	  disk. C: should be the hard disk, or a partition on it, with the
-	  highest priority. This must therefore be the disk with the highest
-	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
-	  original definition of the SCSI-standard as also industrial- and
-	  process-control-machines, like VME-CPUs running under realtime-OSes
-	  (e.g. LynxOS, OS9) do.
-
-	  If you like to run Linux on your MCA-machine with the same
-	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
-	  machine, which is in addition conformant to the SCSI-standard, you
-	  must say Y here. This is also necessary for MCA-Linux users who want
-	  to keep downward compatibility to older releases of the
-	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
-	  June 1997).
-
-	  If you like to have the lowest SCSI-id assigned as drive C:, as
-	  modern SCSI-BIOSes do, which does not conform to the standard, but
-	  is widespread and common in the PC-world of today, you must say N
-	  here. If unsure, say Y.

-	  However, some devices exist, like special-control-devices,
-	  SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
-	  not reset when switched on. If you say Y here, each device connected
-	  to your SCSI-bus will be issued a reset-command after it has been
-	  probed, while the kernel is booting. This may cause problems with
-	  more modern devices, like hard disks, which do not appreciate these
-	  reset commands, and can cause your system to hang. So say Y only if
-	  you know that one of your older devices needs it; N is the safe

-/* fd_mcs.c -- Future Domain MCS 600/700 (or IBM OEM) driver
- *
- * FutureDomain MCS-600/700 v0.2 03/11/1998 by ZP Gu (zpg@castle.net)
- *
- * This driver is cloned from fdomain.* to specifically support
- * the Future Domain MCS 600/700 MCA SCSI adapters. Some PS/2s
- * also equipped with IBM Fast SCSI Adapter/A which is an OEM
- * of MCS 700.
- *
- * This driver also supports Reply SB16/SCSI card (the SCSI part).
- *
- * What makes this driver different is that this driver is MCA only
- * and it supports multiple adapters in the same system, IRQ 
- * sharing, some driver statistics, and maps highest SCSI id to sda.
- * All cards are auto-detected.
- *
- * Assumptions: TMC-1800/18C50/18C30, BIOS >= 3.4
- *
- * LILO command-line options:
- *   fd_mcs=<FIFO_COUNT>[,<FIFO_SIZE>]

-
- NOTES ON USER DEFINABLE OPTIONS:
-
- DEBUG: This turns on the printing of various debug information.
-
- ENABLE_PARITY: This turns on SCSI parity checking.  With the current
- driver, all attached devices must support SCSI parity.  If none of your
- devices support parity, then you can probably get the driver to work by
- turning this option off.  I have no way of testing this, however, and it
- would appear that no one ever uses this option.
-
- FIFO_COUNT: The host adapter has an 8K cache (host adapters based on the
- 18C30 chip have a 2k cache).  When this many 512 byte blocks are filled by
- the SCSI device, an interrupt will be raised.  Therefore, this could be as
- low as 0, or as high as 16.  Note, however, that values which are too high
- or too low seem to prevent any interrupts from occurring, and thereby lock
- up the machine.  I have found that 2 is a good number, but throughput may
- be increased by changing this value to values which are close to 2.
- Please let me know if you try any different values.
- [*****Now a runtime option*****]
-
- RESELECTION: This is no longer an option, since I gave up trying to
- implement it in version 4.x of this driver.  It did not improve
- performance at all and made the driver unstable (because I never found one
- of the two race conditions which were introduced by the multiple
- outstanding command code).  The instability seems a very high price to pay
- just so that you don't have to wait for the tape to rewind.  If you want
- this feature implemented, send me patches.  I'll be happy to send a copy
- of my (broken) driver to anyone who would like to see a copy.
